Specific embodiment
It is described in detail below by specific embodiment, it is to be understood that following embodiments are only used as to the present invention
Explanation and illustration, without limiting the scope of the invention in any form.
As shown in Figure 1, the present invention provides a kind of artificial earthing or grounding means, from inside to outside including core conductive frame, drop resistance object
(4) and shell (5)；The core conductive frame is from top to bottom successively by red copper busbar (1), aluminium busbar (2) and zinc-plated flat
Stainless steel strut (3) is formed by being electrically connected；The red copper busbar (1) is for connecting other earthing or grounding means or need to be grounded
Electrical equipment or electrical system；Full of drop resistance object (4) between the core conductive frame and shell (5).Because of core conductive frame
Fine conductive difference between each component part, under the premise of not influencing thunder and lightning and releasing rapidly, earthing or grounding means of the present invention can
The intensity and speed of thunder and lightning peak current are substantially reduced, so as to fulfill the greatest danger electric current in thunder and lightning to electrical equipment, electrical member
The damage of part.When lightening strikes, red copper busbar accepts room such as the level-one of thunder and lightning peak current, and thunder and lightning peak current is in wink
Between reach after can interrogate speed and import aluminium sheet, this process can arrange the conductive of self-resistance because of red copper and absorb (electric-thermal conversion-cooling stream
Dissipate) and consume part energy.After importing aluminium sheet, thunder and lightning peak current can absorb (electric-thermal turn again due to aluminium sheet conductive resistance
It changes-scatters).Galvanized steel plain sheet is imported from aluminium sheet, hinders object, thunder energy of decaying step by step to drop again from galvanized steel plain sheet.The red copper
Busbar welding, screw connection, riveting or it is other can realize electrically conducting by way of with electrical equipment or other ground connection
Device connects.
The earthing or grounding means of the present invention has multi-path structure, is multi-path state during lightning current invades the device
, it can also be hindered again to drop from copper bar to shell from copper bar to aluminium sheet to galvanized steel plain sheet to drop resistance object (main introduction channel)
Object (shell of such case must be external conductive casing) can also directly invade the channels such as drop resistance object to absorb thunder and lightning spike from copper bar
Electric current.Earthing or grounding means of the present invention is single small, light-weight, is especially advantageous for carrying, it is nearest can be directly mounted at electrical equipment

Vertical and horizontal square crossing connects into the lattice-shaped frame (as shown in Figure 4).In other embodiments of the invention, the red copper is led
Electricity row, aluminium busbar and zinc-coated flat steel sheet plate can be designed to any other suitable shape and structure, for example, red copper busbar
It can be the copper wire of copper wire composition.
In some embodiments of the invention, the vertical and horizontal crisscross of red copper busbar, wears after being connect with aluminium sheet
Drop resistance object is crossed, then outside shell edge extending apparatus, to carry out the endless of all directions such as front, back, left, right, up, down
Integrated assembling.
In some embodiments of the invention, between the zinc-coated flat steel sheet plate and aluminium busbar and the aluminium busbar with
Using being fixedly connected between red copper busbar, it can be welding or known in the art other be fixedly connected with mode.In the present invention
Other embodiments in, between the zinc-coated flat steel sheet plate and aluminium busbar and between the aluminium busbar and red copper busbar
Using being detachably connected, can be bolted, grafting (such as mode of industrial electric connector, socket interface) or ability
Other connection modes known to domain.
In some embodiments of the invention, the shell is external conductive casing, preferably stainless steel plate shell, can also be used
Cast aluminium shell, cast copper shell and galvanized steel plain sheet shell.Wherein, the conductive effect of cast copper shell is best, and usage time is long, but cost
It is high；Stainless steel plate shell low cost, usage time is longer, and conductive effect is general；Cast aluminium housings conductive effect is good, and cost is higher,
But usage time is not as good as cast copper shell and stainless steel plate shell.It is described to be cost-effective in other embodiments of the present invention
Shell can also be insulation crust, for example, using shell made of plastics.The shape of the shell can be come according to actual needs
Design, can be cuboid, square, cylinder or any other suitable shape.
Artificial ground networks provided by the invention, can according to actual needs, by two or more artificial ground connection
Device carries out front, back, left, right, up, down all directions by red copper busbar and is formed by connecting, such as can pass through red copper conduction
The extended segment of row is connected with each other；In the embodiment of no extended segment, it may be used described in the individual components connection of red copper material
Red copper busbar between artificial earthing or grounding means.The artificial ground networks disclosure satisfy that the ground connection of various environment, various capacity
It is required that it can be widely applied to high, precision and frontier light current, strong power system.
